The Oldest and Newest Technologies Combined: Making Object Mounts for Cooper Hewitt

On December 12, Cooper Hewitt Smithsonian Design Museum reopened to the public after a lengthy renovation. One of their opening exhibitions, Tools: Extending Our Reach, features 175 objects that have shaped human life. Creating mounts for the ancient artifacts featured in Tools posed some unique challenges.

The mounts needed to display the object without obscuring it. Due to their age, the objects cannot be handled excessively making measuring difficult, and in the case of hand-carved tools, even if we could handle the objects freely, their uneven surfaces aren’t easy to measure anyway.

So how exactly can OEC make these mounts? How do we know that

Megan Dattoria, OEC mountmaker and 3D printing innovator, is using cutting edge technology to create custom brackets that are a perfect fit for each object. She was kind enough to explain how she makes custom mounts with minimal object handling. (The object in the photos below is a modern interpretation of an ancient stone tool like the one shown above.)



Megan took 45 rotational photographs of the tool. The targets were used to document the object’s scale.


She used photogrammetry software to create a digital file of the 3D model.

Megan printed a model of the tool and worked with that instead of handling the original object. She could hold it and determine its center of gravity.


Megan virtually placed the tool into the correct display position and built the bracket within the program. The resulting bracket corresponded exactly to the tool’s bumps and crevices.


The digital bracket was printed in wax and then cast in brass. Megan painted and padded the final version.


The real object in the mount – a perfect fit!
